Horsehead Nebula

A dark cloud of gas in the shape of a horse head obscures the bright nebula behind it in the Orion star forming region.
The image is a composite of three separate images taken in three different filters (Blue = Johnson B, Green = Johnson V, Red = Cousins R). Each image is a five minute exposure taken with the 20-inch telescope and the U42 CCD camera.
